Application: Toyota Mark II / Chaser / Cresta / Cressida | E-JZX100 | 1JZ-GTE 2.5L Twin Turbo Petrol RWD | Manual Transmission

Part Number: HH010860N / KH010860NU06

The JZX100 platform is a JDM icon — the Mark II, Chaser, and Cresta all share the same capable chassis and the legendary 1JZ-GTE twin-turbo inline-six. Whether it's a Chaser Tourer V being pushed hard on a touge or a Mark II Grande Turbo doing track days, the factory cooling system has its limits when the heat builds.

Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the JZX100, engineered to handle the thermal demands of the 1JZ-GTE in both stock and modified form. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — it retains all OEM fan shroud mounts and stock hose connections with no modifications required.

Why Koyorad?

• Precise Tube & Fin Alignment — Strict quality control ensures optimal coolant flow and maximum heat transfer efficiency across the entire core.
• Nocolok Furnace Brazing — All tubes, fins, headers, and brackets are bonded in a state-of-the-art Nocolok furnace, creating a structure that resists vibration, road debris, and the elements.
• Billet Filler Neck — Precision-machined billet filler necks are fitted to every unit for superior strength, durability, and a reliable seal.
• OE-Specific Mounting — Application-specific mounting points for fan shrouds, inlet/outlet hoses, and top/bottom pins ensure a pain-free, no-modification install.
• Hand-Crafted Heliarc Welds — Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
